Available from August 2022, Jumbo 8000 high-performance loader wagons from Pöttinger can chop forage almost 30 per cent shorter, meaning even higher forage quality without compromising on loading performance. Capable of handling 3,500Nm of torque, these machines can now deliver throughputs greater than self-propelled forage harvesters.
Thanks to a new drive concept, rotor and chopping system with 65 knives, the loader wagons have a theoretical chop length of 25mm, which means the Jumbo 8000 can chop almost 30 per cent shorter than before. This new system requires only 15 per cent more power.
The knives are individually protected and can simply move out of the way of foreign objects. The automatic loading system now features an additional optional sensor on the rotor scraper carrier. This means that up to four sensors – including torque on the rotor, hydraulic pressures and material loading – are used to optimise the loading process.
The new sensor system detects the pre-compaction of the forage directly above the rotor and activates the scraper floor before any mechanical damage can occur. As a result, the Jumbo 8000 can always make optimum use of the space inside the loading chamber, regardless of the type of crop.
When harvesting grass silage, every farm manager wants to obtain the highest possible forage quality to increase profits. One of the main factors influencing feed quality is the theoretical chopped length. This is the advantage of the loader wagon with its short chopped length.
Short chopped forage can be compacted better, which leads to a faster decrease in pH value. This reduces the risk of fermentation failure and has a positive effect on the stability of the grass silage. On the other hand, it has a positive effect on livestock health and performance. So, the new Jumbo delivers a crop with the optimum chopped length, which animals appreciate.
Another yield-boosting advantage of a shorter chopped length is the 10 per cent higher loading density compared to a loader wagon with a conventional chop length of 34mm. The higher payload also adds up to greater cost effectiveness thanks to the higher density. Shorter chopped material also has a positive effect on compaction in the clamp. Less machinery and operator time is needed to distribute and compact the silage.
Despite the relatively small knife spacing of 25mm, it’s still possible to use the AutoCut automatic knife sharpening system. This saves diesel as well as time. AutoCut guarantees the knives are always sharp during operation. The power requirement and the fuel consumption can be reduced by up to 20 per cent as a result.
